okay so 3 months ago my car was dragging butt real bad, hesitating in first and second gear and dying in rainstorms. I thought it might be the fuel filter and so in trying to change that, i pulled the inj 1 and inj 2 fuses because at the time i couldn't find the fuel pump switch. After that, my car would sit there and crank, but would not turn over. After a month of scratching my head i tried one last time and it started up, but ran like hell. The idle is horrible and every time i barely touch the gas pedal it redlines. It threw me a code 33 (MAF) so i changed the sensor and nothing happened. i also changed the o2 as well. i have spark, air, and fuel (43 psi) , but no engine running. did i fry my ecm or is something else majorly wrong?
